Classification of Protozoa: Protozoa are a highly diverse group of eukaryotic unicellular organisms having a wide range of size, morphological characteristics and physiological properties. Protozoans exhibit mainly two forms of life; free-living (aquatic, freshwater, seawater) and parasitic (ectoparasites or endoparasites). They exist as free-living organisms or as parasites. Protozoa is a phylum having unicellular heterotrophs. The term Protozoa was introduced in 1818 for a taxonomic class, but in later classification schemes the group was elevated to higher ranks, including phylum, subkingdom and kingdom.
